Nobody likes to constantly reinvent the wheel. Completely starting from scratch on something you work on all of the time is a waste of time. People reuse parts of old QVWs all the time to save the time & effort of redoing the same things over and over again.
The Dashboard, Analysis, Reporting (DAR) methodology is a foundation you can build all of your applications on while still having room to be creative and meet the varying requirements of individual clients / prospects.
In a nutshell you lead with a Dashboard page, followed by Analysis pages, and finish with Reporting pages. The Dashboard gives the high level overview of the business, the Analysis pages give interactive user-driven controls to filter the data, while the Reporting pages give the most granular details. The system works on a few levels but to understand some of why it works we have to discuss how people interact with computers and how we perceive information. The attached technical paper gives an introduction into Human Computer Interaction (HCI), about Top Down versus Bottom Up perception, and how all of this comes into play in QlikView.
